the price will maybe will go lower, but majority of community is not selling that cheap. There was one big seller, and thats all.
Basically there was a guy asking in this chat three weeks ago Do something with the volume, cuz if I will sell price will go to zero. So probably it was him.
And this price is not comfortable to everyone, it is not enough even to pay for MN. Good thing you can have multiple MNs in each server.
Owning a single MN gives 5.84$ a month with this price, while you pay for service 5$.
